Want to do a good job of keyword ranking, internal reliance on reasonable repetition of keywords, very high content relevance and excellent internal links, external reliance on strong outside the chain of support. In addition, there are many factors that affect the ranking of the keywords are not optimized.
1. Regional differences
Now many websites will automatically identify the visitor's IP to judge its geographical location, the most typical is the group buy network automatically switch city position. Regional differences include at least two aspects: the impact of Baidu on the regional site to judge is the site with regional names, rather than the site's IP; In the case of competing sites of equal quality, regional sites occupy a ranking advantage under the search from searchers in the region.
My IP in Shenzhen, I search arbitrary keywords such as "basketball court", including "Shenzhen" is usually a certain ranking than the national advantage, the fact is so, the ranking of 4-7 are related to Shenzhen.
2. Searchers ' preferences
The search engine records the searcher's search and then determines whether the searcher likes to give different search hints or even return different pages.
The typical impact of this factor is that you can often find your site more than the actual ranking when searching for keywords on your site. Some time ago I input "seo" this keyword, ranked fifth is a weight loss site and lasted 4 days! Combined with the first analysis, the reason is: regional, I am in Shenzhen, this site before the revision is "Shenzhen SEO"; like on, that period of time I do in the weight loss site to do SEO work, weight loss related search more, So Baidu counted this as my "preference".
The same goes for Google and the advertising coalition.
3. Website weight
This is an important factor affecting the ranking of keywords. Domain history, PR, weights, included, outside the chain even Alexa rankings such as the common composition of this element.
For the new station, any one can not compare with the old station (except to buy old domain name), the only solution is to adhere to the update, adhere to do outside the chain, update the law, the chain has a limit, and constantly accumulate the trust of search engines. Think for 2 years, your own station has become an older station?
4. Manual Intervention
The most typical is the various search engine bidding rankings, in addition to the new station for the Google Sandbox, Baidu observation period, and so on cheating site to reduce the right to deal with whether it can count. If there is the same as I impoverished webmaster, the solution is to insist on insisting again!
5. Algorithm adjustment
Each update is a few happy several worry, but according to the previous adjustment of Baidu, it will only pay more and more attention to original content and directly publish the available information site. Therefore, the author to this as the end, intended to alert me and you seoer: Want to do a good job keyword ranking, do not relax site content construction.
